Fe it known that l, 'Citeren B. lllontmat', a citizen ot the llnited States residing at 'Uharleston, in the county ot ltanawha and @tate ot West Virginia, have invented new and useful lmprovements in Sockets, ot which the tollowing is a specication.

ln object ol this invention is to produce an ehicient swivel rope socket tor well tubes wherein the swivel may be readily removed trom the socket when the drill rope is changed trom one string ot tools to another.

t further object is to provide a wire line rope socket and a swivel thereot which will be effectively secured in the Socket `tor nupporting the drillingy rope, hut which likewise may bel readily removed therefrom to permit the drilling rope being changed' l'rom one string ot tools to another vwithout cutting the rope or unscrewing the socket.

".l`he foregoing, and other objects which will present themselves as the nature olf the invention is better understood, ma be accomplished hy a construction, com ination and operative association oli parts such as is disclosed by the drawings which accompany and which torm part ol this specification..

Figure ti is an elevation oi the swivel. l Figure 7 is a plan view ot the percussion block.

"l`he body ot my improved socket is sub-` stantially ot' the ordinary construction and is indicated by the numeral l. rl"he body has at one of itsends a reduced extension torrning a neck 2 and its opposite end provided with a threaded opening 3, commonly known as the box for the pin of other tools. Wll`he neck 2 is provided with a rounded bore il which communicates with the bore ll ol bore 8.

the socket, the bore ll being oi a greater area than the here 3 whereby a shoulder 5 is provided between these bores.

- From one otv its laces, the socket t is provided with an opening o which communicates with the 'bottom of the bore t, and the said tace, in a line with the opening 6 has a vertically arranged slot 7 which also communicates with the bore fl, but which terminates a suitable distance below the shoulder 5. y

'lhe swivel is indicated by the numeral d, the same having a rounded body portion 7' provided with a 'flared `bore 8 and a reduced extension or neck 9 provided with. a bore 10 that communicates with the flared The swivel is ot a size approximately equalling the distance between the lower wall l'ot the opening 6 and the upper wall ot the slot 7, and the body 7 ot the swivel is of a. thickness slightly less than the width of the opening 6, the neck ol the said swivel being ot a thickness slightly less than the width ot the slot 7. By such arrangement, it will he noted that the'swivel may be readily inserted in the bore l ol the socket l. The swivel has arranged therein, in the usual manner, the wire line l1. From the upper end of the slot 7 the socket l and the neck 3 thereof are provid ed with a slot l2, the distance between the parallel walls ot which being greater than the thickness ot the wire line 1l, and it will be thus noted that both the swivel and 4the wire line can be arranged in the bore ol the socket.

When the swivel is received in the bore of the socket l pass through the opening d and into the bore a block 13. This block is of a sudicient thickness to prevent the neck 9 of the swivel entirely passing out ot the bore 3 of the neck 2 ot the socket, and as the block 13 receives the force ot impact from the swivel l will refer to the same as a percussion block. rlFhe percussion block has a central Harige or extension 1l that is received between the walls ot the opening ti. 'lhe percussion block, ot course, rests upon the lower wall lll of the bore d, and like` Wise on the lower wall ot' the opening tl, and passing through openings in the socket and through an opening in the percussion block there is a bolt 15. 'lhis holt is engaged hy a nut le, and preterahly in protill ith

`vided with spaced openings whereby coller pins or like nut locking elements may be arranged thereon.

After the wire line 11 has been set in the lswivel 6 the swivel and Wire line are moved laterally through the o enings and slots as previously described. he swivel will,as previously inferred, rest on the percussion block when the latter is received 1n and secured to thc socket. When so arranged, the outer cud of the neck 9 of the swivel will be flush with the outer end of the neck 2 of the socket. This permits of the neck 2 being engaged by what is known as a combination socket. The fishing socket, in raising, would contact with the neck of the rope socket, enough to break its hold if the neck of the swivel were not extended into the neck of the rope socket. When the weight of tools is on the wire line the neck of the swivel extends through the neck of the socket, and the shoulder between the body and neck of the swivel will contact with the shoulder 5 between the boresof the socket and the neck therefor.

'l`lie socket, above the box box 3 has its sides flanged, as at 16', the flattened surfaces providing wrench holds.

Two sockets will be required on a well,`

one for each string of tools. When it is required to change from one string of tools to the other, it is only necessary to remove the bolt 15, and thereafter remove the percussion block when t-he swivel and the wire line may be taken from one socket and received in the socket for the other string of tools.

With my improvement, it will be lnoted that a great saving of time and labor in changing the swivel from one to another socket is obtained. All of the sockets now in use with which I am acquainted, require screwing up and unscrewing to make the change from one string of tools to another which, of course, requires a large amount of labor and a still larger amount of time. With my socket, it is not necessary to use the large tool wrenches required on the ordinary sockets, as no joints are broken when ren'ioving the swivel from/the socket. Also, it is to be noted that the wire line is not cut when the swivel is removed from the socket, and it is thought that the foregoing description, when taken in connection with the drawings will fully set forth the con' struction, operation and advantages of the improvement to those skilled in the art to which this invention relates.

l Iaving described the invention, I claim 1. The combination, a wire line rope socket having a neck extension and having an interior bore communicating with :i restricted bore in the neck, said socket having an opening communicating with the lower portion of the bore, a slot between the upper wall of the opening which also communicates with the bore of the socket, and a second slot in a line with the first mentioned slot but narrower than the former communicating with the said first mentioned slot, the bore of the socket and ex` tending through the neck, a wire line swivel comprlsing a body and a neck, said body and neck being respectively of sizes lto be passed into the bore of the socket through the o ening of the first mentioned slot, and the llne carried by the swivel designed to be passed into the socket through the last mentioned slot, and a removable block )artially closing the opening and receive in the bore of the socket after the swivel is arranged therein.

2. The combination, a wire line socket having a neck and having a bore inward of the said neck and said neck having a restricted bore communicating with the bore of the socket, said socket having one of its sides provided with an opening in a line with the inner wall of its bore and having a slot from the outer end of the opening also communicating with its bore, said socket from the last mentioned slot having a restricted slotl which communicates with its bore and which extends through the neck of the socket, a wire line swivel comprising a body portion and a reduced neck, said body and neck being of a size to pass into the bore of the socket through the opening in the first mentioned slot and the line carl ried by the swivel being of a size to be passed through the socket .in the last mentioned slot, a percussion block seated iu the socket and in the.- opening, removable means securing the percussion block in the socket. and said percussion block being of a thickness whereby the swivel, when resting thereon will have its neck disposed approximately flush with the outer end of the neck' of the socket.

In testimony whereof I aflix my signature.
